1 Claim.

manipulating handle and suction tube rockably mounted thereon, whereby said head can be conveniently manipulated in confined places and under articles of furniture, radiators, and the like.

Another salient object of my invention is to provide a vacuum cleaner nozzle having a plurality of orifices formed in the front portion thereof, whereby air will be caused to be violently drawn down through the nap of rugs and the like, and thence into the intake opening, and thereby effectively removing lint, hair, dirt, etc. from the article being cleaned.

A further object of my invention is to provide a novel open-throat connection between the suction head and the suction pipe, whereby the suction pipe can be conveniently swung on the head to any desired angle without loss of suction and without undue wear on moving parts.

A further important object of my invention is the provision of novelly arranged bar agitators or runner guides on the lower face of the suction head, the agitators or runners slanting back toward the intake opening to permit the free-passage of air with the conveyed dirt into the suc tion hose, but at the same time preventing the mg or other article from sealing the intake opening.

A further object of my invention is to provide a fiaring vacuum cleaner nozzle in which the air is drawn toward a centrally disposed intake opening, whereby a wide intake nozzle will be had in the front of the head, and a narrow nozzle at the back of the head, whereby the nozzle can be run over the edge of rugs and the like without loss of suction.

A still further object of my invention is to provide a nozzle for vacuum cleaners of the above character, which will be durable and eiiicient in use, one that will be simple and easy to manufacture, and one which can be placed upon the market at a reasonable cost.

With these and other objects in view, the invention consists in the novel construction, arrangement, and formation of parts, as will be hereinafter more specifically described, claimed, and illustrated in the accompanying drawings, in which drawings:

Figure 1 is a top plan view of my improved vacuum cleaner nozzle, showing parts thereof tube ll.

broken away and in section, to illustrate structural detail.

Figure 2 is a side elevational view of my improved vacuum cleaner nozzle, showing parts thereof broken away and in section, illustrating the handle in full lines in its lowered position, and in dotted lines in its elevated position.

Figure 3 is a bottom plan view of the nozzle.

Figure 4 is a central, longitudinal, sectional view through the cleaner nozzle, taken on the line of Figure 1, looking in the direction of the arrows, the view being taken on alarger scale than Figure 1. V

Figure 5 is a transverse, sectional view through the intake-pipe, the view being taken substantially on the line 5-5 of Figure 3, looking in the direction of the arrows, the view being on a larger scale than Figure 3.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the latter N generally indicates my improved vacuum cleaner nozzle, which comprises a suction head It and a combined manipulating handle and suction The head It is formed relatively flat and can be either made from sheet metal suitably bent or stamped into shape, or can be formed from cast material.

The head In includes a triangular-shaped body l2 having a broad, upwardly curved leading edge The body tapers rearwardly from said curved leading edge and terminates in a shoe M. This shoe can also be provided with an upwardly curved flange 85, which acts as a stop for the downward swinging movement of the suction tube H, as will be later set forth.

The body 52 adjacent the shoe M is provided with a transversely extending suction intake opening i5 surrounded by an upwardly extending, rearwardly directed throat ll. Upwardly extending, spaced, parallel side walls 18 are connected with the top surface of the body 42 and extend forwardly from the throat H and engage the opposite sides thereof. The rear edge of the throat M has formed thereon a hinge barrel 19 for the reception of a hinge knuckle 20 formed on the lower transverse edge of the suction tube H. Thus, the suction tube II is free to swing back and forth on the head, and downward swinging movement of the suction tube is limited by its enga ement with the upwardly curved flange IS. The upper forward edge of the tube H has formed thereon a. hinge barrel 2|, which receives a hinge knuckle 22 formed on the rear edge of the sliding closure plate 23. This sliding" closure plate rides between the side walls l8 and on the upper face of the head II. The side edges of the closure plate 23 snugly engage the inner faces of the side walls l8. During the intake of air through the tube H, the plate 23 will be drawn down into intimate contact with the upper face of the body i2, so as to form a seal therewith. If so desired, however, the side edge of the closure plate 23 can carrypins 24 for reception in slots 25 formed in the side walls ll.

and manipulated by an operator. The ribs 21, II, and 29 form means for spacing the head from the rug or other surface being cleaned, and, thus,

Thus, the plate 13 will be positively guided during swinging movement of the tube H.

The rear or shoe portion M of the head can be formed relatively thick, or an extra. piece of metal 26 can be secured to the lower face of the shoe. Extending forwardly from the piece 26 at the side edga of the head II are runners or guide ribs 21. These guide ribs terminate short of the front or leading edge of the nozzle. An inner pair of guide runners or ribs is also ed by the lower face of the head, and these inner ribs or runners terminate in rear of the forward edge of the head, and are disposed on opposite sides of the longitudinal center of the nozzle and substantially at the same angle as the side ribs or runners 21.

Relatively long intermediate runners or ribs 29 are also carried by the head H, and these long intermediate rimners or ribs are disposed between the ribs 21 and 2. and terminate short of the front edge of the head. As shown, the ribs 29 extend back over the intake opening I and are arranged at a greater angle to the longitudinal axis of the nozzle than the ribs or runners 21 and 28.

Staggered rows of orifices 30 are arranged at the extreme front portion of the head and in advance of the ribs or runners 21, 28, and 29. All of these orifices open out through the top and bottom of the head, and their edges are provided with depending lips it, which, in effect, form small guide nozzles and the lips terminating in the same plane as the lower faces of the ribs or runners for engaging the rug or other article being cleaned.

The combined suction pipe and handle II is preferably formed from sheet metal in any approved manner, and the same can terminate in a cylindrical tapered portion 32 for the reception of a flexible suction hose, which can extend to a suitable intake fan (not shown).

My nozzle is of an extremely light construction, and, thus, the same can be conveniently handled prevent the intake opening l6 from being sealed by a rug being lifted into the opening. The guide runners also act as agitators and entirely eliminate the use of rotary brushes and the like, as the runners slide over and agitate the pile of fabric being cleaned.

The spacing of the guide runners or ribs form channels therebetween for the air, and a large intake is provided at the front of the nozzle, which narrows back toward the intake throat II. By this arrangement, the suction through the nozzle is not broken. even where the front of the nozzle rides of! a rug.

Great stress is laid on the orifices II, as these orifices permit air to rush down through the up of a rug or the like. Each orifice functions as a miniature blower nozzle, and lint, hair, thread, etc. is efi'ectively picked up from the article being cleaned. The air moves down into the nap of the rug and then up into the nonle.

The bar agitators or runner ribs increase the air velocity and dirt-getting and -carrying power directly from the orifice II to the intake I of the head. The nozzle will not clog, and all of the orifices are self-cleaning. As heretofore stated, the nozzle takes the place of brushes and moving agitators, which wear rugs and need repairing. All of the parts are open for inspection, and the entire nozzle can be readily cleaned.

The nozzle combines surface agitation with sealed suction cleaning, and, thus, the nozzle does both types of cleaning thoroughly and efilciently without floor drag, which tires the operator and wears out the nozzle. The nozzle will readily adjust itself to diiferent depths of naps in rugs, etc., due to the novel construction thereof.

Changes in details may be made without dcparting from the spirit or the scope of this invention, but what I claim as new is:

A vacuum cleaner nozzle comprising, a substantially flat plate having an intake suction opening, a suction pipe communicating with said opening, said plate having orifices in the front end thereof opening out through the upper and lower .faces thereof, surface-engaging agitating bars on the lower face of the plate extending from the orifices toward the suction opening, and depending lips surrounding the orifices terminating in the same plane as the lower faces of the bars for engaging the surface being cleaned.
